Cape Cod exteriors take more weather load than almost any housing stock in the United States — salt-air corrosion, wind-driven rain from Nor'easters, year-round coastal humidity, and decades-long ultraviolet exposure on south-facing walls. Restoration of the exterior envelope is what keeps a Cape Cod home structurally sound and visually consistent across decades. WM Construction has handled exterior restoration on Cape Cod homes since 2016, EPA RRP lead-safe certified for pre-1978 work, with crews trained in cedar shake, fiber cement, trim profile matching, and coastal-grade flashing detail.
Exterior restoration on Cape Cod is a different practice from new-construction siding installation. A 1950s ranch in Centerville with cedar shake half-rotted on the south-facing wall but sound everywhere else. A Falmouth shingle-style with three decades of accumulated trim rot at the fascia and rake. A Yarmouth Port home where wind-driven rain has worked behind failed flashing on a chimney sidewall and rotted the wall sheathing inside the cavity. A Mashpee colonial where the previous owner's vinyl siding installation 25 years ago is hiding cedar that needs assessment before any new envelope decision gets made.
Restoration work requires diagnostic thinking, not just material selection. The visible failure (rotted clapboard, peeling paint, missing shingles) is usually a symptom of a system problem deeper in the wall — failed flashing at a window head, ice dam damage at a roof valley, a kick-out flashing missing where the roof meets a sidewall, or moisture vapor migration through an under-vented wall cavity. Replacing only the visible failure without diagnosing the cause guarantees the failure recurs within a few seasons.
WM Construction operates from Centerville and approaches exterior restoration as a system. Every project starts with an exterior walk-through that documents siding condition, trim condition, flashing details, roof envelope, water-intrusion paths, and (where applicable) prior repair history. EPA RRP lead-safe protocols apply to all pre-1978 work. Specifications are coastal-grade by default — stainless fasteners, marine-grade primers, properly back-primed cedar — because standard residential materials fail prematurely on Cape Cod's salt-air environment. Every project closes with a written one year workmanship warranty.
Selective replacement of failed cedar shake or shingle siding with new pre-primed coastal-grade cedar, installed with stainless fasteners. Existing sound shingles preserved. 2 to 8 weeks depending on the failed area. Common on south- and west-facing walls.
Cedar clapboard, fiber cement (Hardie), or engineered wood siding restoration. Selective replacement of damaged sections, paint or stain refresh, flashing repair behind affected areas. 2 to 6 weeks depending on extent.
Rotted fascia, soffit, corner board, window casing, door casing, and rake board replacement. Trim profile matching to original where required. PVC trim substitution where appropriate for moisture-prone areas. 1 to 4 weeks.
Kick-out flashing installation at roof-to-sidewall intersections, valley flashing repair, chimney sidewall flashing replacement, and selective shingle restoration around flashing details. 1 to 3 weeks. Often surfaced during siding restoration scope.
Wind, ice dam, and Nor'easter storm damage restoration. Documented for insurance claim coordination: photographs, dated incident reports, and scope tied to the storm event. Emergency tarp / temporary weatherization available. 1 to 8 weeks depending on damage.
Targeted exterior restoration before a property goes on market or before a home inspection. Focused on visible failures, trim rot, paint condition, and known inspector flags. 2 to 6 weeks. Often coordinated against the listing or closing date.
Stainless steel fasteners, marine-grade primers, back-primed cedar, and pre-painted fiber cement are the standard, not the upgrade. Standard residential-grade materials fail prematurely on Cape Cod's salt-air environment, so coastal specs are written into every proposal.
The visible failure is usually a symptom. We diagnose the system cause — failed flashing, missing kick-out, vapor migration, ice dam damage — before specifying the repair, so the failure does not recur within a few seasons of the restoration.
Exterior sanding and paint scraping nearly always crosses the 6 square foot disturbance threshold on pre-1978 homes. WM is RRP-certified; containment, HEPA cleanup, and documented disposal are built into every applicable project.
Photographs, dated incident reports, and scope-to-storm-event documentation provided in the proposal package so homeowners can pursue any available insurance claim with proper paperwork. Age-related restoration documented separately so the proposal is clear about what is and is not insurance-eligible.

Exterior restoration pricing on Cape Cod varies with the scope of failure and the depth of envelope work required. A targeted trim rot repair on a small section is one range. A full envelope restoration involving cedar shake, trim, flashing, and selective sheathing repair is a fundamentally different range. The variables that drive cost on Cape Cod specifically:
Cedar shake versus alternative siding material is one of the largest specification choices. True cedar shake (Western Red or Eastern White) is the iconic Cape Cod look and lasts 30+ years with maintenance, but costs significantly more than fiber cement or vinyl alternatives. Coastal-exposure cedar should be selectively back-primed and installed with stainless fasteners; skipping either accelerates failure. Replacing failed cedar with composite alternatives in HDC-controlled exterior locations is often not permitted.
Flashing detail and selective sheathing repair is often the hidden cost driver. Pulling failed siding usually reveals deeper damage — rotted sheathing, compromised house wrap, failed window flashing, or kick-out flashing missing at sidewall-to-roof intersections. Diagnostic exposure is included in the assessment phase so the homeowner sees what's behind the visible failure before approving the scope.
Trim profile matching on older Cape Cod homes drives cost more than expected. Original 1950s and earlier trim profiles are not stocked at modern lumber yards. Hand-milling to match (or sourcing through specialty millwork suppliers) adds material lead time and labor. For homes inside historic district commissions (Sandwich, Barnstable Village, Falmouth, Yarmouth Port, Dennis Village, Brewster, Chatham, Provincetown), profile matching is often required, not optional.
Pre-1978 EPA RRP lead-safe protocols apply to most older Cape Cod homes. Exterior sanding and paint scraping nearly always crosses the 6 square foot disturbance threshold. Containment, HEPA cleanup, and documented disposal are required by federal law and included in the line-item proposal — not absorbed silently or skipped.
Roof envelope condition often comes up during exterior restoration. Cedar shingle roofs, asphalt shingle valleys with failed underlayment, missing kick-out flashing, and compromised ridge venting are commonly identified during siding work and addressed in the same project where they affect siding longevity. Roof work coordination is documented separately in the contract.
Storm damage versus age-related restoration matters for insurance coordination. Damage from a documented storm event may be covered by the homeowner's insurance policy and requires specific documentation (photographs, dated incident reports, scope tied to the storm date). Age-related restoration is not insurance-eligible. We document both clearly on the proposal so the homeowner can pursue any available insurance claim with proper paperwork.
Every WM Construction exterior restoration proposal is a written line-item contract — section by section, material by material, with coastal-grade specifications, a permit profile, and a target completion week.
WM Construction handles exterior restoration on Cape Cod homes across Barnstable County and into Plymouth — Centerville, Barnstable, Falmouth, Mashpee, Yarmouth, Dennis, Brewster, Harwich, Chatham, and Plymouth. Our office is in Centerville and our exterior crews work each week within roughly an hour of the showroom. Coastal-grade specifications (stainless fasteners, marine-grade primers, back-primed cedar) are the default for every project. Pre-1978 homes are handled by EPA RRP-certified crew leads. For homes inside town historic districts, we coordinate the HDC application before exterior work begins.
True cedar shake (Western Red or Eastern White) installed correctly with back-priming and stainless fasteners typically lasts 30 to 40 years on Cape Cod, with periodic maintenance every 3 to 5 years to address weathered areas. South- and west-facing walls weather faster due to UV and salt exposure. Skipping back-priming or using non-stainless fasteners cuts that lifespan in half or worse.
We document both during the assessment. Storm damage is typically localized to one event area (a single roof slope, one wall section facing the wind direction), has consistent damage pattern, and ties to a documented storm date. Age-related failure tends to be cumulative across the exposure surface, more progressive, and not tied to a single event. The distinction matters because storm damage is often insurance-eligible while age-related restoration is not.
Yes, but it requires custom millwork. Original Cape Cod trim profiles from before roughly 1980 are not stocked at standard lumber yards. We either hand-mill to match using a router with custom-ground bits, or source through regional specialty millwork suppliers with lead times of 4 to 8 weeks. HDC-controlled homes typically require exact profile matching.
Depends on location. For moisture-prone areas — bottom courses, near grade, around ground-floor windows — PVC trim is a defensible choice for longevity, as long as the home is not in an HDC district that requires wood. For visually prominent or HDC-controlled trim, wood (pre-primed and back-primed) is the preservation-correct answer. We make the recommendation case by case during the assessment.
Yes. We provide photographs, dated incident documentation, and scope tied to the storm event so the homeowner can submit a claim with proper paperwork. We do not file insurance claims on the homeowner's behalf, but we provide everything an adjuster needs to evaluate the scope. Emergency tarp or temporary weatherization is available for active leaks.
Yes, federally, on any pre-1978 home where the work disturbs more than 6 square feet of painted exterior surface — which is nearly every exterior restoration project on an older Cape Cod home. WM is RRP-certified and the protocols (containment, HEPA cleanup, documented disposal) are built into every applicable proposal.
Yes. For homes inside Sandwich, Barnstable Village, Falmouth historic district, Yarmouth Port, Dennis Village, Brewster Center, Chatham, or Provincetown historic districts, we file the HDC design review application before any exterior work permits are pulled. We coordinate the commission feedback and material specification approval as standard practice on those projects.
Call WM Construction or send photos of the affected exterior areas with notes on when you first noticed the issue. We respond with a building assessment, a diagnostic plan, insurance documentation if applicable, and a written line-item proposal.
